<P>PROBLEM TO BE SOLVED: To perform driving support with a simple structure while improving convincing of a user. <P>SOLUTION: An information acquisition part 22 acquires information indicating a position of an own vehicle from a GSP device 12 as well as road information including a regulation speed, road structure and road width around the own vehicle from an electronic map data system 14, and a hazard selection part 24 selects hazard candidates corresponding to the regulation speed and the road structure. A passable area width calculation part 26 obtains margins corresponding to the selected hazard candidates and calculates an area width through which the own vehicle can pass by subtracting the margins from the road widths. A target passage speed calculation part 28 calculates a target passage speed according to the passable area width; a support determination part 30 determines whether driving support is acceptable or a support level according to a deceleration obtained from the passable road width or the target passage speed and a current speed; and a support control part 32 controls so that the driving support according to the determination result of the support determination part 30 is executed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
